ROTARY MOTOR.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed January 31, 1907. Serial No. 355,038.

To all whom it may concern:

Be it known that I, ADELBERT SAUER, a citizen of'the United States, and resident of Pittsbur in the county of Allegheny and State of l ennsylvania, have invented an Improved Itotary Motor, of which the following is a specification. i

My invention relates to improvements in that class of motors or turbines in which rotary piston is driven by the impact and reactionary force of steam or other motive fluid. It is more particularly an improvement upon the motor for which. I have received Letters Patent No. 783,984, dated February 28, 1905. I have devised and put in successful use several improved features of construction, whereby new and. superior results are obtained.

The details of construction; arrangement and operation of the improved motor are as hereinafter described and illustrated in the accompanying drawings, in which Figure 1 a central vertical longitudinal sectionof the motor. Fig. 2 is 'aperspective view of the rotary piston a portion of the )eripheral sleeve or cylinder thereof being shown broken away. Fi 3 is a vertical transverse section on the line 33 of Fig. 1. Fig. 4 is a diagrammatic pl- 11 view showing a peripheral portion of the piston in section and extender in the flat. 1 ig. 4 is a detail section. illustrating the arrangement of induction slots or openings in the casing, through which the motive fluid has access to the rotatable body of the motor. Fig. 5 is a corresponding view showing modification.

A cylindrical shell A is su )portcd upon parallel vertical plates 1 that form the ends of a condensing chamber. Within the said shell is arranged. (mncentrically a casing B which is spaced from the shell by circumferential ribs 2 between which is formed the space for reception of the steam or other metwo fluid through the pipe 23. Thus the casing B is fixed with the shell. The latter has caps 4 which are chambered to form passages for steam or other motive fluid, and the bottom or under side of the shell is provided with slots 5 throughwhicl'i the spent steam or other fluid escapes into the condenser. In respect to the construction and arrangement of the parts thus far described, my present invention is similar to that for which I have obtained Letters Patent as aforesaid.

The rotary motor (,see Figs. 1, 2 and 3 is mounted upon a shaft D having its bearings in the shell caps 4 as in my former invention, but the said piston. distinguished by novel and improved features of construction as will nowbe described. Steam. is admitted to the piston through slots 6, one of which is shown in Figs. 1 and 4. There is a series of said slots, all inclined tangentially to the wheel or body of the engine and spaced apart equidistantly, and extending around the cas- 66 ing circumferciitially formed in that portion of the casing B which lies between the circun'iferential ribs 2, and as in the former invention the steam thus admitted acts upon a series of longitudinal wings 7, and passes 70 thence through side ports 8 formed in circ umfcrential ribs 9 that abut the ends of the wings 7sce Figs. 1 and 4-. There is a series of such peripheral ribs 9 arranged radially and parallel to each other and duly spaced apart, as will be seen by reference to Figs. 2 and 4. The several ribs are con nected transversely by-wings, as each. are ar ranged alternating in position, that'is to say, each one being opposite a pocket or space on each side.

The ports 8 in the several ribs 9, are arranged at an angle, say 45, and in such rela tion to one of the wings of an adjacent pocket that steam or other motive fluid pass 35 ing through a port will strike upon the center of said wing, sce dotted lines Fig. 4. The steam or other fluid thus acting by impact on a wing 10, passes through the next port 8 inan adjacent rib, and then impinges on the next wing, as will be readily understood. Thus, the steam leaving the middle pockets formed between the central radial wings 7, passes spirally around a considerable portion of the pistons on both sides of the central 9F pockets and by its reactirmary effect as in turbines of well known construction, the cylinder is propelled with corresponding rapid ity. By the diagonal or inclined arrangement of the several ports 8 in the peripheral ribs 5) and the arrangement of the Wings 10, I secure a maximum propulsive effect, and thoroughly utilize whatever pressure the motive fluid may have.

In place of arranging the ribs and wings of the piston to work in contact with. the casing B, as in my former invention, I incasc them by a cylindrical sleeve E, save only the outermost series of wings 10'--see Figs. 1 and 2. The main advantage attained by the use of the sleeves, is that steam or other motive fluid cannot escape or leak between the piston proper and 'the surrounding casing B, but must pass the entire length of the piston from the center outward, whereby the greatest propulsive effect is produced and the pressure of the steam is fully utilized. The terminal wings 10 are not incased by the sleeves E, but extend radially to the casing B, and no ribs close the ends of the pockets or spaces between said wings whereby the largest available space is left for their expansion and escape of the steam or other 'fluid which has acted upon all the other wings 10. Thus while the steam acts by impact on the terminal Wings 10 in the same manner as on. the wings 10, it also has free escape into the passages by which reaches the discharge openings or slots 5 in the under side of the shell A.

As shown diagrammatically in Fig. 5, wings 11 may be arranged at an inclination "instead of a right angle to the ribs, and steam ports 9 may be arranged at the intersection of the ribs and wings and at such an angle that if their (X be extended they would be at a right angle to the wings 11, as indicated by dotted lines in Fig. Thus in either form of construction, the pcripheryof the piston O is provided on each side of the center or middle portion with a series of ribs and wings which are cast integrally with the shell or body of the piston and in every case the ports whereby steam passes through the ribs are arranged to deliver it directly upon the central portion of a wing in the adioining pocket. By this mode of CO3'1St1UCtl(.)Il also the cylinder may be produced cheaply.

The condenser proper F is constructed as in my previous invention, cool or cold water being received through pipe 1 into a space or chamber 13, passing thence through horizontal pipes 14 into a corresponding space or chamber 13, and escaping in a heated condition through pipe 15. A pipe 16 is shown. connected with the pipe 15 at one end, and with the condensing chamber proper It at its other end. tend to the boiler, and a vacuum pump will be connected therewith for forcing heated Water obtained directly from the chamber 13 and also the water of condensation drawn through pipe 16-.
